Specification of Letters Patent.

Application filed June 1S, 1908. Serial No.'439,214.

To all whom it may concern.'

Be it known that we, Josine-ius C. PLANK and Trioims E. FULGHUM,citizens of the' United States, residing at Grand Junction, in thecounty of Mesa and State of Colorado, have invented a new and usefulHeater, of which the following is a specification.

l This invention relates to heaters and'is designed more especially foruse in orchards for the purpose of preventing injury to trees andplantsas a result of sudden frosts.

The object of the vinvention is to provide a simple, durable andeiiicient device of this character which is cheap to manufacture, andwhich can be readily placed in position and filled with the fuel to beused for heating the surrounding atmosphere.

A further object is to provide a device of this. character which is soconstructed as to enable an efficient draftto circulate therethrough andthus reduce to the minimum the smoke produced by combustion andcorrespondingly reduceA the amount of smut accumulating upon 'the treesand which is sometimes injurious to the buds.

A further object is to provide a device of this character having a grateof novel form designed to retain the fuel, the entire device includingthe grate being formed of a miniinum number of parts.

With these and other objects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter' more fully described and pointed out in the claims.

-In the accompanying drawings is shown the preferred. formof the.invention.

'In said drawings: Figure l is a central vertical section through aheater embodying the present improvements. Fig.A 2 is a plan Viewthereof, a. portion of the cover being broken away.

teferring to the figures by characters of reference, l designates thebody of the heater, the same being preferably formed of a length `ofsheet metal having its ends lapping. and held together by rivets 2 or inany other preferred manner, said body being in the form of an invertedcone frustum. Arranged within the small end portion ofthe body are crossstrips 3 arranged at right an-1 gles to each other and preferably heldtogether at their centers by a rivet 4 or in,l any other preferredmanner. These cross strips are provided at their ends with legs eX-'tending at rightv angles therefrom and riveted or otherwise secured tothe inner face of the body l. These legs extend beyond the small end ofthe body and are provided with feet G extending' inwardly therefrom atright angles and constituting broad bearing surfaces for contacting withthe ground. Those portions of the body between the legs are bentinwardly or crimped as indicated at 7, these inwardly extending portionscooperating with the cross strips 3 to support fuel within the body .andabove the ground. lt is thought that this will be clearly apparentbyreferring to Fig. 2. A cover 8 may be provided for the body 1, the samehaving a handle' 9 extending therefrom whereby it can be readily placedin or remove-d from position. Any suitable means suoli as depending ears10 may be provided upon the cover for projecting into the upf per end ofthe body and thus preventing the cover from becoming displaced after'be#ing placed in position. As shown in the drawings these ears arepreferably produced by striking them downward from the peripheralportion of the cover, although it is to be understood that they. may beformed in any other manner desired. l

When it is desired to use the device herein described the same is placedat a convenient,

point within an orchard and filled with wood, charcoal, coal or anyother material constituting the fuel and when this fuel is once igniteda sufficient draft will be maintained through the heater to supportcombustion and at the same time reduce the quantity of smoke generated.Thecombus tion may be controlled by partly or entirely opening the coverS. It is designed to place fifty or sixty heaters such as hereindescribed in each acre and eaclrheater is designed to be suiiicientlylarge to contain enough fuel to lastv five to seven hours. As the heateris formed of sheet metal it can be cheaply manufactured and it will benoted thatJ the same is very simple in construction inasmuch as itconsists of but three pieces exclusive of the cover, said pieces beingvarranged invsuch a manner as to-form the body, the legs, and the grate.

What is claimed is:

1. A heater comprising a body, cross strips secured in one end portionthereof, and legs integral with and depending from said strips andsecured' to and extending beyond "the body, said body having depressedportions between the legs and cooperating with the cross strips toconstitute a grate.l

2. Aheater comprising an inverted frustoconical body having angulardepressions- I therein at its lower end, cross strips secureddiametrlcally Within the body and coperating. with the depressions toconstitute a grate, legs integral With said strips and secured 'to andextending' beyond the body,

g and feet integrali with said legs.

3. Aheater comprising an inverted frustoconical body having angulardepressions therein at its lower end, cross strips secured diametricallywithin the body and coperating with the depressions to con titute grate,legs integral with said strip and secured to and extending beyond thebody, feet Iintegral with said legs, a cover, retaining JOSEPHUS C.PLANK.
